ecosystem : the complex of a community of organisms and its environment functioning as an ecological unit — Webster
Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia
Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.
A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia
Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. — Wikipedia

New method to predict the vulnerability of...

The susceptibility of ecosystems to disruption depends on a lot of factors that can't all be grasped. A new method provides good results with only limited information about the properties of predators. The model confirms that a large body mass index between predator and prey creates stable systems. It can also predict which predator species play a key role. […]

Scientists say that subsistence hunting in Neotropical rain forests -- the mainstay of local people as a source of protein and a direct connection to these ecosystems -- is in jeopardy from a variety of factors. […]
Protecting rare species can benefit human life
on May 16, 2019 at 7:53 pm
Preserving rare species for the sake of global biodiversity has long been the primary focus for conservationists. To better protect rare animals, insects and plants, and to prepare for an uncertain future influenced by climate change, a team of researchers is aiming to merge this conventional wisdom with a new way of thinking: arguing researchers needs to better understand how rare species benefit people outside of their existence value.

Land use is at the core of various sustainable development goals. An international research group has endeavored to disentangle the key determinants of global land use projections. […]
How plants are working hard for the planet

Mapping the global distribution of phytoplankton
on May 16, 2019 at 2:23 pm
Researchers at ETH have charted the distribution of phytoplankton in the world's oceans for the first time and investigated the environmental factors that explain this distribution. They concluded that plankton diversity is only partially congruent with previous theories of biodiversity for the seas between the equator and the poles. […]

Baboons are large, smart, ground-dwelling monkeys. They are found across sub-Saharan Africa in various habitats and eat a flexible diet including meat, eggs, and plants. And they are known opportunists – in addition to raiding crops and garbage, some even mug tourists for their possessions, especially food. […]

on May 15, 2019 at 5:00 pm
In and around the tangled roots of the forest floor, fungi and bacteria grow with trees, exchanging nutrients for carbon in a vast, global marketplace. A new effort to map the most abundant of these symbiotic relationships—involving more than 1.1 million forest sites and 28,000 tree species—has revealed factors that determine where different types of symbionts will flourish. The work could help scientists understand how symbiotic partnerships structure the world's forests and how […]
